Common hepatic duct

Dr Craig Hacking and Dr Lawrence Oh et al.

The common hepatic duct is formed by the junction of the right and left hepatic ducts. It joins the cystic duct to form the common bile duct.  It is approximately 4 cm long and 4 mm in diameter. 

Together with the cystic duct  (laterally) and cystic artery (superiorly), they form Calot's triangle.
